Guys, I have resolved the problem with the help of this article. I am explaining what methods I applied to solve the issue.

First I checked the system file by following this command sfc /scannow, then run DISM scan using these commands:

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

Then reinstalled the gaming service. It was miracle! After following these methods correctly, when I tried to reinstalled the game, there was no system file error which I was getting first. Now I am enjoying playing the game with my son.
